I see the font color change didn't make it - everything after "the
signal routes through coaxial cable W24..." should be blue.

From the 5371A manual, which uses the same 54002A input pods:
The HP 54002A 50 ohm input pod is electrically a dead short. The input
signal terminates into 50 ohm resistance (A2R42)
ONLY after the HP 5371 A is powered on. After passing through the input
pod, the signal routes through coaxial cable
W24, joins cable W19 at the forward chassis bulkhead, and continues on
through cable W19 to connector A2J1. The
input signal then travels in one of two directions. If the 1:1 (0 dB)
attenuation setting is selected, relays A2K1 and K2
short CHANNEL A attenuator A2Ul out of the circuit. In the 2.5:1 (8 dB)
attenuation setting, A2U1 is placed in
series with the CHANNEL A input signal. This setting allows the
application of an input signal with a peak voltage of
2.5 times the normal operating range. Immediately following relay A2K2,
the input signal is sampled and routed to
the Al Timebase Control Board's Overload Sense circuit via signal path
OVER V A. This circuit protects the A2
Input Amplifier by opening relays A2K1 and K2 when the input voltage
exceeds the nominal value of ¡À2.7 Volts. See
Path Selection (Relay Control) circuit description for more details.
Everything after the blue font is probably different in the scope but
the pods are the same.
Hope this helps!

Thanks Gary. Do you know if the output from the probe pods to the main
frame is 50 ohms? If the 54002A pods are a direct feed through that
would verify it. I don't have the scope but am awaiting arrival of a
54001A probe that I want for general use after I make a power supply.
The manuals are a bit sparse on details but I think the output is 50
ohms.

Hello, does anyone have or know of a site where I can get a scam
of a
manual for the HP 54001A 1GHz probe or the HP54100D scope it's
used in.
It's particularly the probe info I need but the scope would also be
useful too.
Thanks, Don Black.
